6 Claims.

This invention relates to' a reflector for electric lamps primarily for out of door use. My reflector is adapted for mounting at the upper end of a standard and comprisesy not only the vreflecting member itself, but the supporting means therefor which also carries a socket for positioning an electric lamp within the reflector. A characteristic of my reflector is that it has at Y Y, its upper end a drum of reduced size, or monitortop, as I prefer to designate it, with a lateral window in it, so that in addition to reecting the light downwardly it may throw a beam laterally.

My reector is especially well adapted for use in filling stations having external pumps, the reector being adapted to illuminate the pumps and adjacent region and also throwing light toward the accompanying building. The invention is illustrated in the drawings hereof and is hereinafter more fully explained and the novel features are summarized in the claims.

In the drawings, Fig. 1 is a sectional side elevation of one form of the reflector proper and its support in position on top of an upright tubular post; Fig. 2 is a horizontal section through the post looking upwardly at the reflector, as indicated by the line 2-2 on Fig. l; Fig. 3 is a vertical section through the monitor top of the vreflector of Fig. 1, as indicated by the line 3-3 on that figure; Fig. 4 is a detail in enlarged section of the connection between the supporting rods and the reector proper; Fig. 5 is a fragmentary sectional side elevation of a reflector having a modified form of monitor top.

As shown in Figs. 1 and 2, A designates a suitable upright supporting post or standard. Attached to the upper end of this post is a fitting Iii, carrying the socket l2 for the lamp B. The fitting is a tubular member adapted to extend over the upper end of the post to which it is clamped by a set screw I5, passing through a reduced collar-like portion I6 of the fitting. Internally, the fitting has a transverse web I7 with an opening I8 for the passage of the electric conductors b and screw-threaded openings for the reception of screws I9 holding the socket in place.

The reflector proper in either form comprises a flaring lower portion or skirt 2t and a cylindrical upper' portion 2I, closed at its upper end by a slightly curved crown portion 22. Below this monitor top the aring portion preferably extends laterally while curving downwardly in dish-form for some distance as at 23 and then extends downwardly in a more abrupt conical (Cl. 24U-103) shape 24 terminating at a beaded lower edge 25.

A suitable lateral opening 26 is formed in the vertical wall of the monitor top to provide a window, and preferably behind this opening is v an arcuate transparent pane 36 of glass or similar 5 material. This pane may be held in place by suitable clips 3i engaging the lower edge, and clips 32 and 33 engaging its end edges. When constructed as illustrated in Figs. l and 3, the u bottom clips SI and one of the end clips 32 are 10 permanently secured to the reflector while the other end clip 33 is removably held by screws or other means, thus enabling the pane to be readily mounted or replaced, as desired.

To hold the reflector described in proper posi- 15 tion relative to the lamp B, I provide three rods 45, secured at their lower ends to the fitting Iii and at their upper ends to the lower portion 2li of the reflector. These rods have lower end portions iI bent at an vangle to the main body of 20Y the rod, these lower portions extending through vertical openings in a projecting collar i2 of the fitting, the rods being held in position by set screws 23. At theirouter ends each rod has secured to it, by welding or brazing, an eirter- 2.- nally threaded bushing t5. Embracing this bushing is an internally threaded sleeve lie, which alsol embraces the externally threaded inner end portion of a plug it which extends through an opening in the reiiector wall and has an enlarged head on theV outer side thereof. This makes a Very neat and effective meanst` of connecting the reflector to the supporting rods. The necks of the plugs 4l are merely passed through openings in the reflector and then the sleeves, which 35 have been screwed well onto the bushings 55, are unscrewed from those bushings and screwed onto the plug extensions so that the reector becomes tightly clamped between the sleeve and head of the plug. 40

The adjustment permitted by the described method of clamping the reiiector, and the adjustment permitted by the vertical portions of the supporting rods through the collar of the fitting, enable the reflector to be accurately po- 45 sitioned with reference to the fitting and thereafter rigidly held thereon.

It will be noticed that in the embodiment of Fig. 1, the reflector with its monitor top and transparent pane presents a continuous imper- 50 forate structure, thoroughly water-tight from top to bottom. However, if desired, I may make ventilation openings through the cylindrical surface of the monitor top. Such construction is shown in Fig. 5, where these ventilation open- 55 ings are shown at 50. In this case I prefer to surmount the monitor top with a protecting hood 5l in order to prevent passage of rain or snow into the ventilation openings. This 'hood is of scoop-shape, having a downwardly curved crown sheet and a wall 52, which is U-shapedv in horizontal cross-section; that is to say, for the most part this wall is cylindrical and concentric with the monitor top but adjacent the window diverges to leave a flaring open spaceV with the wall of the hood spaced from the cylindrical wall of the monitor top, and thus provides an effective space for ventilation, at the same time preventing access of rain or snow to the openings 52.

It will be noticed that with either embodiment of my reflecting member, the monitor top with its crown and the flaring skirt of the reilector may be one integral member, for instance, of metal with enamel facing. The supporting ritting may be a single integral casting. All other parts'of the construction are simple and readily applied. My reiiector therefore may be cheaply constructed; there is nothing about it to get out of order, and experience has demonstrated it is very eiicient when installed.

I claim:

1. A relector having a flaring skirt portion and a monitor top in the form of a cylindrical drum with a crown, ventilation openings and a light transmissive Window through the cylindrical wall of such drum, and a hood over the monitor top having a crown portion and a depending skirt and spaced from the crown and cylindrical wall of the monitor top said hood Haring outwardly adjacent the window to permit the direct passage of light therefrom and yet protect the ventilation openings from the weather.

Such construction holds the crown of the 2. A reector made of one continuous integral piece of metal and having a lower conical portion, a dish-shaped portion leading inwardly and upwardly from the conical portion, a round, concentric upward extension from the dishshaped portion, and a top for said extension, the extension being provided with a lateral window, a translucent pane within the extension and extending across the window,l and means on the interior of the extension for holding the pane in place. i

3. A reflector made of one continuous integral piece and having a lower conical portion, a dishshaped portion leading inwardly from the conical portion, a round concentric upward extension from thedish-shaped portion having ventilation openings, and' a top for said extension spaced a substantial distance from said extension to provide ventilation, said extension being provided with a lateral window and a light transmissive closing means for said window.

4. The combination of a reecting member having a flaring skirt and a monitor top with a lateral 'window and Ventilating openings, a pane of light-transmissive material covering said window, meansfor supporting the reflecting member and for supporting an electric lamp in such position that some kof the rays of the lampV pass directly through the window in the top and a hood to protect said window from the weather, said hood l being substantially spaced from said monitor top to permit ventilation throughv said Ventilating openings.

5. A reector having a flaring skirt portion and a monitor top with ventilation openings and a light-transmissive window in said top, and a hood over said'top and flaring outwardly adjacent the window to permit direct passage of light therethrough and yet protect the ventilation opening from the weather.

6. A reflector shell, having ventilation openings and a light-transmissive window, a hood carried by said shell and substantially spaced therefrom to cover said ventilation openings and yet permit access thereto of air and said hood ilaringoutwardly adjacent the window to permit direct passage of light therefrom and yet protect the ventilation openings from the Weather.
